Re: Data assurance (T10Pi) performance impacts

Attaching the support data file. 

Re: Data assurance (T10Pi) performance impacts

Could you send that support bundle to me directly, please. You can send it to daniel.landes@netapp.com

 

Thanks,

Danny

Re: Data assurance (T10Pi) performance impacts

Could you also get a screenshot of the segment size you're using for your volumes and your caching options.

 

You can get this information from SANtricity System Manager. Go to Storage --> Volume (highlight any volume) --> View/Edit Settings --> advanced tab

 

Thanks,

Danny
